Functional Classification of Joints01:09

Functional Classification of Joints

7.1K
Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses  or amphiarthroses, whereas all synovial joints are classified as diarthroses.

siRNA - Small Interfering RNAs

18.8K
Small interfering RNAs, or siRNAs, are short regulatory RNA molecules that can silence genes post-transcriptionally, as well as the transcriptional level in some cases. siRNAs are important for protecting cells against viral infections and silencing transposable genetic elements.
In the cytoplasm, siRNA is processed from a double-stranded RNA, which comes from either endogenous DNA transcription or exogenous sources like a virus. This double-stranded RNA is then cleaved by the...

lncRNA - Long Non-coding RNAs

10.0K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

piRNA - Piwi-interacting RNAs

7.7K
PIWI-interacting RNAs, or piRNAs, are the most abundant short non-coding RNAs. More than 20,000 genes have been found in humans that code for piRNAs while only 2000 genes have been found for miRNAs. piRNAs can act at the transcriptional and post-transcriptional levels and have a vital role in silencing transposable elements present in germ cells. They are also involved in epigenetic silencing and activation. Previously, they were thought to function only in germ cells but new evidence suggests...

Background:

  • Genomes are pervasively transcribed, producing numerous long noncoding RNAs (lncRNAs).
  • DNA regulatory elements like enhancers and promoters initiate bi-directional transcription.
  • Distinguishing functional lncRNAs from the vast transcriptome is a significant challenge.

Purpose of the Study:

  • To provide a conceptual and experimental framework for classifying and elucidating lncRNA function.
  • To categorize lncRNA loci based on their regulatory mechanisms (cis vs. trans).
  • To propose experimental strategies for dissecting lncRNA activity.

Main Methods:

  • Review of current lncRNA research and methodologies.
  • Classification of lncRNA loci into cis-acting and trans-acting.
  • Proposal of experimental approaches to analyze lncRNA function.

Main Results:

  • A framework for classifying lncRNA loci based on their mode of action (cis or trans).
  • Proposed experimental strategies to investigate lncRNA roles.
  • Highlighting the potential of these strategies to uncover novel biological insights.

Conclusions:
